Appendix F. Comparison of ATAG 1.0 checkpoints to ATAG 2.0

This mapping shows how the ATAG 1.0 checkpoints relate to the ATAG 2.0 Working Draft. Note that ATAG 2.0 is still a draft and the ATAG 2.0 Guidelines and success criteria in no way supersede the checkpoints in ATAG 1.0.

The Working Group is working carefully to enable developers that are currently using ATAG 1.0 (which remains a stable and referenceable document) to ensure that they will be able to make a smooth transition to ATAG 2.0 when it is released.

Comparison Table

Requirements in ATAG 1.0 Recommendation

Location of Requirements in ATAG 2.0 Draft

Guideline 1. Support accessible authoring practices.

PRINCIPLE B.1 (Production of accessible content must be enabled)

1.1 Ensure that the author can produce accessible content in the markup language(s) supported by the tool. [Priority 1]

Removed because this is covered by WCAG 2.0, which ATAG 2.0 references.

2.3 If markup produced by the tool does not conform to W3C specifications, inform the author. [Priority 3]

Removed because the real issue is the accessibility of the web content, not the organization that produced the specification. The accessibility of markup produced by authoring tools is covered by Guideline B.1.3 (Ensure that automatically generated content is accessible). The most relevant success criteria are: B.1.3.1 (Level A), B.1.3.2 (Level AA), and B.1.3.3 (Level AAA).

Guideline 3. Support the creation of accessible content.

PRINCIPLE B.2 (Authors must be supported in the production of accessible content)

Now covered more generally by Guideline B.2.3 (Assist authors in repairing accessibility problems) and also by success criterion B.2.1.2 (Set Accessible Properties: Mechanisms that set web content properties (e.g., attribute values, etc.) also can be used to set the accessibility-related properties. (Level A)).

3.2 Help the author create structured content and separate information from its presentation. [Relative Priority]

Now covered more generally by Guideline B.2.3 (Assist authors in repairing accessibility problems.)

7.1 Use all applicable operating system and accessibility standards and conventions (Priority 1 for standards and conventions that are essential to accessibility; Priority 2 for those that are important to accessibility; Priority 3 for those that are beneficial to accessibility).
